Abstract: This application has disclosed a method for sending and transmission of a resource conflict indication and a communication apparatus. When determining that a reserved resource indicated by first SCI conflicts with a reserved resource indicated by second SCI, a first terminal device sends an RCI to a second terminal device at a determined time domain and/or frequency domain position before a conflict position; or when determining that a resource corresponding to first SCI conflicts with a resource corresponding to second SCI, a first terminal device sends an RCI to a second terminal device at a determined time domain and/or frequency domain position after a conflict position. The RCI is sent at the determined time domain and/or frequency domain position.

Abstract: Embodiments of this application provide a time unit determining method and a communication apparatus. A network device indicates a time unit that is in a predefined time unit set and that belongs to a new radio network vehicle to everything (NR-V2X) resource pool to a terminal device, and indicates a time unit that is in the NR-V2X resource pool and that belongs to a long term evolution network vehicle to everything (LTE-V2X) resource pool to the terminal device, so that the terminal device can determine a time unit that is in the predefined time unit set and that belongs to both the NR-V2X resource pool and the LTE-V2X resource pool. According to the method, in a scenario in which LTE-V2X and NR-V2X coexist, conflicts between an NR-V2X resource and an LTE-V2X resource are reduced, thereby improving data transmission reliability.
